T0 whom it may concern.-

Be it known that I, ALoYs I-IAGE, residing at Hildesheim, Germany, have invented certain new and useful Improvements in or Relating to Sectional Boilers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a sectional boller for kitchen-ranges and is intended both for large and small houses. It is distinguished by great adaptability to most varied requirements.

Everywhere where the kitchen-range has to be used for heating large quantities of water for rinsing or bath purposes or heating large hot closets forwarmingup food or crockery or for heating living-rooms 1t is neces sary that the heating body should be capable of adapting itself to these various requirements. Thus it is necessary to provide for the hot water required for rinsing in the kitchen, and also for the water for the bath,v

and in many cases also for heating hot closets, &c., while in the winter it is also necessary to heat some of the living-rooms.

This device is also intended to make it possible to use it within wide limits for culinary purposesthat is to say, chiefly for cooking food since, for instance, in large hotels or clubs the demands on the kitchen vary to a great extent.

An apparatus fulfilling the above requlrements is the subject of this invention and 1t consists of a section-boiler which is built into the range and provided with several furnaces, which can be operated either lndependently of each other or simultaneously, and the parts of which--walls', grates, ash-pitsare cooled by the contents of the boiler, and at the same time heat the said contents of the boiler,while the said parts are then protected against be coming incandescent. One of these furnaces is considerably larger than the rest and is suitable for heating the whole contents of the boiler, while the other furnaces act only on a comparatively small portion of the heatingsurface of the boiler. All the furnaces are, however, arranged in such manner that their combustion-gases can be utilized for heating the range-that is to say, for heating the range plates and roasting and warmmg stoves, heating baking-stoves, kettles, and generally for any other purposes.

same boiler on line A B of Fig. 1.

Another feature of the apparatus according to this invention consistsin the fact that when one furnace-for instance ,only the large one is used the parts of the smaller one are also heated that is to say, act as aheating bodyand that for the purpose of regulating the heating action of the flames any desired number of the furnaces could be made to act more or less on the contents of the boiler and cprrespondingly less or more on the rangeate.

p Several constructions of a sectional boiler according to this invention are illustrated in the accompanying drawings, in which Figure 1 is a vertical section through such a boiler transversely of the furnaces. Fig. 2 Fig. 3 is a is a horizontal cross -section through the vertical section through the same boiler on line C D of Fig. 2. Fig. 4 is a vertical section through another construction of the sectional boiler. Fig. 5 is a vertical section through the same boiler on line E F of Fig. 4. Fig. 6 is a vertical section through a third construction of the sectional boiler transversely of the furnace, and Fig. 7 is a vertical section through the fourth construction of the sectional boiler transversely of the furnaces. Figs. 1, 2, and 4 show, in addition to the boiler, some other parts of the rangefor instance, roasting and warming stoves-the remaining figures not showing any extra parts except the range-plates.

The boiler illustrated in Figs. 1 to 3 consists of partly-similar and partly-dissimilar hollow sections filled with water, arranged side by side, communicating with each other by means of openings at 1). Single boiler-sections when placed together form, in the wellknown manner, a large combustion-chamber g, which is closed at the bottom by a grate h, through which water circulates. This chamber forms the large furnace, which heats-the whole contents of the boiler. The sections also form projections which constitute a sec- 0nd grate t for the small furnace 7c,-which is arranged considerably higher close to the range-plate, so that only the-upper portion of the contents of the boiler is heated by the same smaller furnace, chiefly by the heating action of the incandescent fuel on the grate.

Under the large grate h is an ash-pit f and under the small grate a similar ash-pit u, the said ash-pits also being formed by the hollow projections or parts of the boiler-sections.

The large furnace is closed at the top; but, if desired, it can be open at the top, and thus form a shaft -furnace. Combustion-gases from the large furnace pass into i'lues Z m, arranged between the sections, the flues Z leading upward from close above the grate and then passing into the downward flues m.

, At the highest point, where the two flues join,

are arranged openings n, which can be closed by dampers 0, the combustion-gases passing, when the dampers are open, direct under the range-plate p and acting here with the greatest portion of their heating power. When the openings in question are closed, the combustion-gases go downward and heat hirther the water contained in the boiler.

In order to utilize further the combustiongases escaping downward from the flue m for the extra heating of the contents of the boiler, there are arranged between the parts of the boilersections,which form the bottom limit of the ash-pit u, slots 1), which are normally closed by a plate or damper w, arranged on the bottom of the ash-pit. By opening the said slots or openings 12 the combustion-gases escaping from the flues m can follow the path (shown by dotted arrows) through the small furnacethat' is to say, through the ash-pit and the grate-bars of the small furnaceso that the gases can give off the remainder of their heat now to the said parts of the furnace.

According to the position of the dampers 0 it is therefore possible either to utilize the whole heat produced on the grate h for heating the boiler or to convey it to a greater or less extent under the range-plate or the roasting-stove, &c., or to use it on the one side for heating the boiler and on the other side for heating the range-plate or a roasting-stove.

r r are roasting or warming stoves, which can be surrounded and heated by the combustion-gases both from the small and from the large furnace.

The boiler in Fig. 4 is distinguished from the one just described both by the symmetrical arrangement of two smaller furnaces 7c, arranged at the top, one at each side of the boiler, and by the arrangement of a third small furnace 00 below the furnace on the lefthand side. This latter furnace is a gas-furnace, the space as containing any desired number of burners y. The combustion-gases from this furnace normally follow the path indicated by the arrows, (shown in full lines,) while after the removal of the plate 10 they follow the path indicated by the dotted arrows through the upper small furnace. Such a boiler is suitable for being arranged in the center of a large range, so that its combustion-gases would act to either side.

Fig. 5 is a longitudinal section through the small furnace Zc. It also makes clearer the arrangement of the boiler in Figs. 1 to 3. Fig. 5 also shows the outlet-openings for the downward 'iiues m into the spaces arranged under the small furnaces and communicating with the main fine, as well as the slots 12 between the section parts g and the plate w closing them.

In the boiler shown in Fig. 6 the small furnace 7c is arranged above the large furnace g and is separated from it by a partition which is also constituted by boiler-section partss, through which circulates water. Between the section parts s are again arranged slots o, normally closed by a plate or damper w, so that they can be opened by removing the said plate, when the combustion-gases'from the large furnace 9 will pass through the small furnace 7c.

There are no outer or adjoining furnaces; but they could be arranged, in which case the number of combinations between the different furnaces could be increased to a large extent.

Finally, the boiler shown in Fig. 7 is also provided with two superposed furnaces, of which the smaller one is at the top and open at the top, but is not separated from the bottom one by a partition. hen the large furnace is used, either all the combustion-gases from the same are conveyed through the up and down flues Z and m, arranged between the sections, or admitted under the rangeplate by means of the dampers 0, or pass entirely or partly between the slots of the gratebars i under the range-plate 29, so that the sections of the small grate i become heatingbodies by means of which the combustiongases of the large furnace are utilized.

As already stated, it is possible to combine in various manners the constructions illustrated, thus producing new forms, without departing from the spirit of this invention.

The special shape of the boiler-sections and the kind of furnaces, whether grate-furnacesor gas-furnaces, is immaterial, It is only necessary that there should be a boiler, consisting of separate sections, in which the separate parts of the furnace are portions of the boiler-sections.

What I claim is- In a boiler, the combination, with a series of sections arranged side by side and provided with water-spaces connected by upperand lower cross-tubes a and Z), said section forming a main combustion-chamber 9, upwardly-extending flues Z, and downwardlyeXtending i'lues m; of an auxiliary combustion-chamber Zc arranged above the level of the said combustion-chamber g, a rangeplate arranged over both the said combustion-chambers, dampers at the upper ends of the fines Z and m permitting the products of combustion to pass from said chamber g to the range-plate, a damper arranged below In testimony whereof I affix my signature the combustion-chamber 7c and permitting in presence of two Witnesses. the products of combustion to pass through the said chamber R from the said combustion-chamber g, and a discharge-outlet for I ALOYS HAGE.
